COMPOSITION PACKING.

SPECIFICATION forming part of Letters Patent No. 763,277, dated. June 21, 1904.

Application filed February 12, 1904.

To a, whom it may concern:

Be it known that I, WILLIAM L. GILE, a citizen of the United States, residing at Muskegon, in. the county of Muskegon and State of Michigan, have invented new and useful Improvements in a Composition of Matter for Packing, of whichthe following is a specification.

v This invention relates to a new and useful composition of matter used in forming packing for pistons 0f steam-engines and other places where the steam and air tight packing is desirable.

It also relates to a completed packing composed of the ingredients and constructed in the manner hereinafter described.

To more clearly illustrate the packing, reference is bad to the accompanying drawings, in which Figure 1 is an elevation, partly broken away-, of a packing-ring constructed in accordance with this invention; and Fig. 2 is a cross-section of the ring.

This composition of matter consists of the following ingredients prepared and combined in substantially the same proportions stated, to wit: antimony, five parts; tin, twenty parts; lead, sixty-seven and one-half parts; asbestos, five parts; graphite, two and one-half parts. The lead, tin, and antimony are first melted together and about one-third of the same is cut into strips, while the balance is prepared in solid globules, preferably of varying sizes. The asbestos is shredded, and the graphite is prepared in small particles of any suitable shape. The ingredients above described are then thoroughly mixed together, so as to form a heterogeneous mass.

. The composition, composed of substantially the portions and prepared in substantially the forms above described, is placed in molds or formers and subjected to a high pressure, so as to be formed into rings or shapes adapted to fit the different-sized pistons'to which the same are to be applied. The rings or formedup portions of packing are then in suitable forms to be used and may be packed and shipped as a complete article of manufacture.

The preparation and article above described is adapted for use in connection with steam- Serial No. 193,347. (No specimens.)

acters,'A denotes-the inside of the packing,

and B the periphery; C, the metallic globules or pellets of varying sizes; D, the flexible metallic strips cut in the form of thin ribbons;

E, shredded asbestos, and F the graphite.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent of the United States, is

-1. A molded heterogeneous packing-ring consisting of antimony, tin and lead combined in the form of flexible binder-strips, antimony, tin and lead combined in the form of metallic globules, shredded asbestos, and a lubricant.

2. A molded heterogeneous packing-ring consisting of antimony, tin and lead combined inthe form of flexible binder-strips, antimony, tin and lead combined in the form of metallic globules of varying sizes, shredded asbestos, and a lubricant.

3. As a new article of manufacture, amolded and compressed heterogeneous packing consisting of metallic globules, metallicflexible binder-strips in the form of ribbons, shredded asbestos, and graphite in small particles.

4. As anew article of manufacture, amolded and compressed heterogeneous packing consisting of metallic globules of varying sizes, metallic flexible binder-strips in the form of ribbons, shredded asbestos, and graphite in small particles.

'In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM L. GILE.
